Flat and Solid Shapes

Mathematicians in Room 117 have been hard at work learning about 3 dimensional (solid) shapes.  We been describing them, composing them, and comparing them to 2 dimensional (flat) shapes.

During math workshop, students rotated through four stations to strengthen their skills of sorting 3D shapes, composing shapes and pictures with 2D shapes, and identifying 3D shapes in pictures.

I think the favorite activity was the building station!  Students had to use their imagination and construct with our 3 dimensional foam shapes and then record the shapes they used.

My smart students even surprised me by finding 3D shapes during snack time!

To culminate our shape unit, students had a choice.  They could go on a shape hunt with our Gordon College intern, Zoe, or create a Chatterpix sharing information they learned about a shape of their choice.

On their shape hunt, they found many solid shapes around the school...

and even some flat shapes too!

Mrs. Nichols and I worked with the students who wanted to use Chatterpix to share what they learned about shapes.

We are becoming quite the shape experts!

What shapes can you spot in your house or while you are outside for a walk on a beautiful, sunny day?

CCSS.Math.Content.K.G.A.2
Correctly name shapes regardless of their orientations or overall size.
CCSS.Math.Content.K.G.A.3
Identify shapes as two-dimensional (lying in a plane, "flat") or three-dimensional ("solid").
CCSS.Math.Content.K.G.B.4
Analyze and compare two- and three-dimensional shapes, in different sizes and orientations, using informal language to describe their similarities, differences, parts (e.g., number of sides and vertices/"corners") and other attributes (e.g., having sides of equal length).
CCSS.Math.Content.K.G.B.5
Model shapes in the world by building shapes from components (e.g., sticks and clay balls) and drawing shapes.
